Turbine flow meter installation and piping requirements

Abstract: The information on the installation and piping requirements of the turbine flow meter is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. Installation and piping requirements of turbine flowmeter ①The uneven distribution of flow velocity and the existence of secondary flow in the pipe are important factors that affect the measurement accuracy of turbine flowmeter. Therefore, the turbine flowmeter has certain requirements for the upstream and downstream straight pipe sections. For industrial measurements, upstream is generally required. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the installation and piping requirements of turbine flowmeters. Installation and piping requirements of turbine flowmeter ①The uneven distribution of flow velocity and the existence of secondary flow in the pipe are important factors that affect the measurement accuracy of turbine flowmeter. Therefore, the turbine flowmeter has a certain effect on the upstream and downstream straight pipe sections.—Set requirements. For industrial measurement, the straight pipe length of 20D upstream and 5D downstream is generally required. In order to eliminate the secondary flow, it is best to install a rectifier at the upstream end. If the upstream end can be guaranteed to have a straight pipe section of about 20D, and a rectifier is installed, the measurement accuracy of the flowmeter can reach the accuracy level at the time of calibration. ②The turbine flowmeter has high requirements on the cleanliness of the fluid, and a filter must be installed before the flowmeter to ensure the cleanliness of the fluid. The filter can be a funnel type, and its own cleanliness can be obtained by measuring the change of the differential pressure at both ends. ③ In order to ensure that the liquid passing through the flowmeter is single-phase, that is, no air or vapor can enter the flowmeter, an air eliminator should be installed upstream of the flowmeter when necessary. For liquids that are easily vaporized, a certain back pressure must be guaranteed downstream of the flow meter. The size of the back pressure can take twice the pressure drop of the flow sensor under the maximum flow rate plus 1.2 times the vapor pressure of the liquid to be measured under the maximum temperature. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Turbine flow meter installation and piping requirements'
